As part of many patients’ routine eye exam, we typically include a screening visual field test of what you are able to see peripherally. This is commonly referred to as “side vision.” Visual field tests assess the potential presence of blind spots (scotomas), which could indicate eye diseases.
Many eye and brain disorders can cause visual field abnormalities. For example optic nerve damage caused by glaucoma creates a very specific visual field defect. Other vision problems associated with blind spots developing within the visual field include optic nerve damage (optic neuropathy) from disease or toxic exposure or damage to the light-sensitive inner lining of the eye (retina). We have found that conducting this test routinely at each full eye exam enables us to detect many eye conditions that might otherwise have been difficult to detect.
